SINGLE-RAIL ELEVATED-RAILROAD GIRDER.

.To all whom it may concern:

Be it known that I, JOHN FISH, a citizen of the United States, residing at Summit, in the county of Union and State of New Jersey, have invented a new and Improved Lattice Girder for Single Rail lllevated Railroads, oit which the following is a speeication.

My invention relates to improvements in lattice-girders as used for single-track ele vated railroads; and the object of my inven tion is, rst, to attach the T-traek rail to the upper member of the girder, formed of two angle-irons in a secure and efiieient manner, and at the same time not to weaken either the rail or the angle-iron by drilling holes in the top flanges of either, second,to form a supporting-bracket for the track of the outer bearing-wheels, which will give lateral stili'- ness to the girder. I attain these objects by the mechanism illustrated in the accompanying` drawings, in whieh- Figure l represents a side elevation of part of the girder, Fig. 2, a cross-section taken through a b on Fig. l. Fig. 3 is an outside view of angle-brackets N N, attached to supporting-bar E, and also the attachment of supporting or suspension bar to angle-struts I I. Fig. 4 represents plan of top view ot' girder. Fig. 5 represents a section of angleiron, A A, in Fig. 2, in which is a recess for receiving wooden packing-strips H I-I.

Similar letters refer to similar parts in the several views.

In the drawings which illustrate my invention, A A A A represent angle-irons, forining the upper and lower members ofthe girder. Interposed between the vertical flanges ofthe upper angle-irons ofthe girder is a strip of iron, B, of about half the depth of the angle-ange, and slightly thicker than the web of the T-track rail upon which the center wheels of the engine and cars run.

The lattice angle-bars C O C O and suspension T-bars E E are riveted securely at their upper ends to the angle-bars, and the flat bar B placed between them. rllhis leaves a channel-way above bar B and between angles A A, into which the web of the traek-rail D iits when secured in position. Under the FECIFICATION forming part of Letters Patent No. 328,395, dated October 13, 1885.

Application filed January 15, 1885.

Serial No. 152,944. (No model.)

ilanges of track-rail D are placed liners of wood to deaden the noise and jar, as the engine and cars run over the track. To keep the wooden liners in position, and to prevent them from working out sidewise, channels are formed in angles A A, as shown in Fig. 5, or indentations F F, in the flanges ofthe trackrail by a punch forming dowels, as shown in Figs. l and 2. These lit into the wooden liners and secure them. A drawbolt, G, with split eotter, is used to draw the track-rail down upon the wood liners H H, so that if it is necessary to replace a worn out or broken rail, by simply backing out the draw-bolts G G and lifting the rail ont oi' its recess another rail can be placed in position withoutl disturbing any other part of the structure. rIhe lower parts of the lattice-bars C Care riveted to the lower angle-irons, A A', nothing being interposed between them. rPhe ilanges of the end of suspension T-bars E E are cut from the web and bent up at a suitable angle to meet the anges of the strut angle-bars I I, and riveted thereto, while the web of the suspension-bar is interposed between the ver tical flanges of strut-bars I I, and the three parts are also riveted together, forming a stiff, strong, and secure junction at these outer points of the strut. The struts I I are also securely fastened to the lower angles by riveting.

Outside of and above the junction of the suspension-bar E and strut-bar I is the channel-bar J, resting upon and riveted to the strut-bar I. rlhe channel-barJ supports and carries the longitudinal wooden beam K with its wearing-piece L, upon which run the outer beaiingwheels, M. Upon each side o1' the web ot' the suspension E is placed an anglebracket, N N, which gives support to the wooden beam K, and braces the channel-bars J .I.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In the upper member of a girder for a single-rail elevated railroad, the combination of the angle-irons A A, with arecessed channel for holding wooden or other packing in place, and plate B, with the traek-rail I), sub- ICO with the suspension-bars E E, substantially as constructed and arranged, and for the purpose as herein set forth.
